Does anyone have issue with Potplayer and the new drivers nvidia 358.87 ? I have prender always at 0 ( GPU 95% with madvr and EVR , non CUVID or DXVA Back-to)
EDIT Never mind, I think something with Asus GPU Tweak 2 messed thing up, after restart everything ok including the overclock Last edited by x7007; 6th November 2015 at 04:17. Reason: fixed |

I'd like to see more film examples too. Are there not any movie watchers here?
From Cube (1997) Original at 100% https://c2.staticflickr.com/6/5743/2...133b4b6a_o.png xbr75 doubling, then Catmull + LL+AR downscaling https://c1.staticflickr.com/1/746/22...6e5980ff_o.png xbr100 doubling, then Catmull + LL+AR downscaling https://c1.staticflickr.com/1/627/22...845b12c0_o.png No upscaling refinement, sorry. I think 100 is more faithful, but a tad too sharp. Last edited by JarrettH; 6th November 2015 at 04:45. |

But the image is definitely not offensive. It is very sharp, though, to be certain.

I did some comparisons with SuperRes and nnedi3 (32 neuron) to demonstrate the problem with Sharpness 1. All of these are also radius 0.66 and linear light unless otherwise indicated.
No SR (alignment off because nnedi3 introduces pixel shift) : http://i.imgur.com/wS8TZUw.png Str 4 Sharp 1: http://i.imgur.com/q9Q0elg.png Str 4 Sharp 2: http://i.imgur.com/Q9IP9JU.png Str 4 Sharp 3: http://i.imgur.com/pQdX4EW.png Str 4 Sharp 4: http://i.imgur.com/86MVCvM.png Str 4 Sharp 1 Radius 0.33: http://i.imgur.com/zCoqUCg.png Str 4 Sharp 1 Radius 0.33 (extremely obvious bugs on the old man): http://i.imgur.com/W2xMJJF.png For all of these, the easiest area to spot the enhancements/bugs is around the white hat. IMO, Sharp 2 is closest to the original in terms of edge enhancement. Sharp 1 looks broken. Sharp 3 and 4 are similar sharpness, and enhance the ringing beyond what's in the source.

Anyone can tell me what is the best setup for 1080p content? For 1080p content on 1080p screen does chroma superres work without upscaling? And i am a bit confused what is the difference in chroma superres and upscaling refinement superres?

There will be little to no difference unless you are using SuperRes. SuperRes is more effective when used with Image Doubling.

The brightness increase totally vanishes if I run AdaptiveSharpen in linear light. So my impression is that the fix implemented by bacondither is not sufficient yet. If you have a different opinion then please post comparison screenshots where using the shader HLSL files shows less brightness increase than madVR's implementation, although you've carefully matched sharpeness strength.

Today many Blu-Rays are relatively clean with only low amount of ringing. I think for those super-xbr should work pretty well. If you are watching a lot of low quality content with strong ringing in it, then obviously NNEDI3 is the much better choice for that. Quote:
I wouldn't say that. Using sharpness values over 75 should not introduce artifacts. But it might enhance already existing artifacts. Which is a quite important difference. Quote:

http://madshi.net/SuperResTest.png I've been using this test image to do some more SuperRes related tests. Here are my conclusions: 1) Linear light vs gamma light: If you downscale the image in LL, and then use SuperRes with GL, the lines get too thin. If you downscale the image in GL, and then use SuperRes with LL, the lines get too thick. The only way to reproduce the proper line thickness is to use either GL or LL for both downscaling and SuperRes. Which means that unfortunately I will probably not be able to remove the "linear light" SuperRes option, because the optimal value will not be the same for all sources. 2) Using linear light, different SuperRes sharpness values produce different artifacts. It seems that a sharpness value of 2 produces the least amount of artifacts. 3) A radius of 0.66 produces some aliasing. A radius of 1.00 means SuperRes adds no aliasing, but SuperRes also loses some of its effectiveness/sharpness. Values between 0.66 and 1.00 show some aliasing and some sharpness loss. I'm not sure which radius I should use. Maybe a compromise would be 0.80 or something like that? Quote:

I'm wondering whether I should remove the SuperRes sharpness setting again and hard code it to 2, since it seems to be the one which produces the most faithful reconstruction of the "ground truth"? |

What are the advantages of "dithering in linear light"? Or more generally: What is linear light good for when it comes to dithering? What happens to the picture if I choose "don't dither in linear light" under "trade quality for performance"?

These videos aren't readily available since I had to download them off twitch and Youtube, but maybe I can make a reduced sample. Unfortunately that might involve large parts of the video to find where it goes wrong, which I'm not sure I have time for.

It would also be great if chroma SR could get the same update as luma SR if any possible please. |

How to improve image quality?
Hello, anyone have any suggestions to improve my settings?
LAV filter decoder=software. madVR DX11 FSE (1080P24/1080P60) Output: 10 bit madVR + 12 bit Nvidia control panel -> Sony Bravia XBR-46HX929. SD: • Chroma: Jinc + AR • Image: Jinc + AR • Double Luma: 1.2x or greater - NNEDI3 64 Neurons • Double Chroma: 1.2x or greater - NNEDI3 32 Neurons • Quadruple Luma: 2.4x or greater - NNEDI3 64 Neurons • Quadruple Chroma: 2.4x or greater - NNEDI3 32 Neurons • Downscaling: Catmull-Rom + AR + LL • Upscaling Refinement: Adaptive Sharpen (strength: 0.2) • Artifact Removal - Debanding: Low/High • Image Enhancements: Off • Dithering: ED2 + Use Colored Noise 720P: • Chroma: Jinc + AR • Image: Jinc + AR • Double Luma: 1.2x or greater - NNEDI3 64 Neurons • Double Chroma: Off • Downscaling: Catmull-Rom + AR + LL • Upscaling Refinement: Adaptive Sharpen (strength: 0.2) • Artifact Removal - Debanding: Low/High • Image Enhancements: Off • Dithering: ED2 + Use Colored Noise 1080P: • Chroma: Jinc + AR • Image: Jinc + AR • Double Luma: Off • Double Chroma: Off • Downscaling: Catmull-Rom + AR + LL • Upscaling Refinement: Adaptive Sharpen (strength: 0.2) • Artifact Removal - Debanding: Low/High • Image Enhancements: Off • Dithering: ED2 + Use Colored Noise There is some advantage in using Super-xbr in Chroma? What is better NNEDI3 + Adaptive Sharpen or NNEDI3 + SuperRes?

madshi
My config: W7, AMD 15.2 driver The problem: When source is video (29,97) and "force video mode' option is on, display does not switch to 59 rate, but swtches to 23. If I set to 'video mode' using keyboard shortcut display switches. |

However, "mostly" is not "always" though. I don't know from what medium the Lighthouse example, which Warner306 posted, originates, but it shows some nasty haloing with super-xbr and it doesn't seem to be a crappy web video. Quote:

I don't know about such fines structures. Maybe it is correct that they look aliased when they are upscaled, since this could be how the image would look like if it was created in that size in the beginning? Maybe it's just a problem with very tiny pictures (or huge scaling factors). Quote:
However, with content "in the wild", I've found the thickening of LL SR more annoying than the brightness increase of gamma light in the meantime. Image gets brighter, but unlike traditional sharpen filters, it doesn't look "bleached" to me. And white fonts hardly become thicker with GL SR unless they are really on a very dark to black background, unlike black letters with LL SR. Quote:
Quote:
This can make sense however with very low-res content or high scaling factors. What about simple heuristics that decide the radius depending on the scaling factor? With a high scaling factor, the effect of SuperRes is much more perceivable, so the slight regression of sharpness wouldn't hurt. Quote:
Hm, but there could be the case when you want to use SuperRes, but can only afford 2 passes, and still you don't want to miss out on some additional sharpness. In this case, a sharpness of 3 could still make sense. Would probably still look better than additional LumaSharpen. |
